6 Snorkeling Spots Sheltered From Summer Swells

6 Snorkeling Spots Sheltered From Summer Swells

Summertime on Maui usually brings perfect weather for beautiful beach days. But, summer swells can present a challenge for many of our favorite snorkeling spots. What to do? Auntie Snorkel is here to guide you to some of the best snorkeling spots where you can glide through calm, crystal-clear waters even during summer swells. So, get your snorkel gear ready for an epic adventure without the worries of rough waves. But first, let’s get a better understanding of where those summer swells come from, and where they’re likely to have impacts.

Where Do Summer Swells in the Pacific Ocean Come From?

In Maui, summer swells are largely influenced by the seasonal shifts in weather patterns and ocean currents. During the summer months, typically from May to September, the southern hemisphere experiences its winter season. This naturally produces stronger and more frequent storm systems that in turn generate deep ocean swells that travel northward. These winter storms, often originating near Antarctica or in the southern Pacific, create powerful swells that can travel thousands of miles across the open ocean. As these swells propagate northward, they reach the Hawaiian Islands, including Maui, where they produce the summer swells that surfers and ocean enthusiasts eagerly anticipate.

Summer swells in Maui that travel long distances are characterized by their longer period, which refers to the time interval between successive wave crests. This longer period results in more powerful and well-defined waves compared to the shorter-period swells common from closer storms or wind near shore.

The south and southwest-facing coastlines of Maui are particularly affected by these summer swells. Areas such as Ka’anapali, Lahaina, and Olowalu on the western side of the island, as well as Kihei, Wailea, and Makena on the southern coast, receive the brunt of these south and southwest swells. These locations are favored by surfers for their consistent waves and generally favorable wind conditions during the summer months.

So, Where Can I Snorkel When a Summer Swell is Present?

First, the bad news. If the south swells are up AND the weather is bad at the same time, there might not be anywhere suitable for snorkeling. In that case, scroll all the way down to the end of this article for our favorite snorkeling alternatives. However, the good news is as long as the weather is decent, there are quite a few snorkeling spots that typically avoid summer swell impacts, mostly on Maui’s northwest shore.

South Shore

Snorkeling spots on Maui’s south shore (Kihei-Makena) are not as sheltered from summer swells as the northwest corner of Maui. So, more often than not, there are likely to be waves at your favorite south Maui spot if a south swell comes in. However, neighbor islands can heavily shadow some swell directions. In this case, for example, snorkeling spots closer to Kihei could have minimal waves, when Wailea and Makena have large surf. This is why it’s imperative to check the forecasts for the day and the days ahead, so you can make informed decisions about where to safely snorkel.


How Can I Find Out About Summer Swells Ahead of Time?

Weather and Waves KiheiFortunately, surf forecasting has become quite good, alerting us up to 2 weeks ahead of time when a large swell is on the way.
